Hi there solve both and use GRASS acronym!

1. Two dynamics carts are placed end to end. Cart 1 (1.2 kg) is stuck to cart 2 (1.8 kg). Cart 1 is pushed with a force of 18.9 N [W], causing cart 1 to push cart 2 forward Ignore the force of friction. (a) Calculate the acceleration of each cart. [ans: 6.3 m/s[w]] (b) Calculate the force that cart 1 exerts on cart 2. [ans: 11 N [W]] (c) Would your answers change if cart 2 were pushed with an equal but opposite force instead of cart 1? If your answers change, calculate the new results. [ans: 6.3 m/s [E); 7.6 N [W]] 2. A 1200 kg car is moving at 95 km/h when the driver notices a deer down the road. He immediately moves his foot toward the brake pedal, taking only 0.50 s before the car starts slowing down. The brakes cause a net force of 2400 N [backwards] on the car for 2.0 s. The deer then jumps out of the way and the driver lifts his foot off the brake pedal. How far does the car move in the 2.5 s starting from when the driver sees the deer? w fans: 62 m]
